WATER-POWER WHEEL.

SPECIFICATION forming part of Letters Patent No. 447,810, dated March10, 1891.

Application iilecl J'une 17, 1890. Serial No. 355,766.A (No model.)

To @ZZ whom t may concern:

Be it known that we, JOHN DAHLQUIs'r, a citizen of the United States,residing near Portland, in the county of Multnomah, State of Oregon, andOLoF N. DAHLQUIsr, a citizen of the United States, residing at Tucker,in the county of Oowlitz and State of Tashington, have invented certainnew and useful Improvements in \Vater-Power Wheels; and we do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

Our invention relates to water-power wheels adapted to run in any streamof running water and to be operated by the natural current of thestream.

The object of our invention is to produce a water-power wheel having aseries of paddles pivotally secured in a suitable frame, and a mechanismto throw the paddles out of working position, the whole being placed andsecured in a frame having slotted standards, which are secured betweentwo piles, thus enabling the whole frame to be lifted bodily out of thewater for repairs, dto.

By the mechanism above mentioned the wheel can be stopped without takingit out of the water; and with these ends in view our invention consistsin the parts and combination of parts, as will be more fully described,and pointed out in the claims.

In the accompanying drawings, Figure l is a vertical central sectionthrough the wheel and supporting-frame. Fig. 2 is a longitudinal centralsection through the same. Fig. 3 is a side elevation of the shortlocking-rod. Fig. 4 is a side elevation of the long lockingrod.

A represents the top and bottom of the su pporting-frame 5 B, the sidepieces thereof. The said side pieces B are eachprovided with a groove b,by means of which the frame can be slid down and be secured between twopiles, (not shown,) and can be readily hoisted out of the water whennecessary.

O is a shaft having bearings in the top and bottom pieces A of theframe. Around the shaft C are secured circular plates D, between whichare secured arms D', connected at their outer extremities by means ofcircular bands d. These circular bands dare connected with each other bymeans of standards d', to which are hinged the paddles E and F. Thesepaddles E and F, constituting an upper and lower series of paddles, arearranged alternately with respect to each other. The paddles areprovided with projections e and f, respectively. The circular plates Dare slotted around the shaft O, and above' the upper circular plate D isa sleeve G, havingv extensions g and g', the said extension'g restingdirectly upon the plate D. This extension g is slotted like the platesD.

H is a locking-rod, which is passed through the slots in the extension gand some of the plates D and serves to lock the upper series of paddlesE. This rod H is provided with notches h.

H is another locking-rod, which extends through the slots in extension gand all of the plates D and serves to lock the lower series of paddlesF. This rod H is provided with notches h.

Pivoted to one of the side pieces B at 7l is a cross-beam I, having acentral aperture, by means-of which it is secured loosely around shaftIO. The sleeve G extends up through this cross-piece I and is secured toit by means of the extension g', which rests directly on the cross-beam.The other end of this cross-beam I works in a slot or opening` B in theother side piece B.

Secured to the beam I is a staple t", to which is connected a rod i,working` in an opening A in the top of the frame.

The operation of our Water-power Wheel is as follows: The pileshereinbefore referred to, but not shown, are iirst secured in the streamin which it is desired to place the wheel, the wheel being secured inthe frame as described. The frame is then slid down between `the pilesand is held in position between them by means of the grooves b in theside pieces B. The paddles on one side of the wheel are, by means of theprojections e and f, resting against the y up side 7 ofv thelocking-rods H and I-l, or, in other words, against the side of thelocking-rodsv toward which the current is running. The current nowstarts the wheel and bears against each IOO and every paddle in its turnuntil the paddle gets parallel with the current, the wheel stillrevolving. The current of the stream then throws the paddle that isparallel with it out of place and swings it out, so that it offers no,resistance to the current and passes up edgewise against the current.It will be readily understood that the current acts only on the paddleson one side of the wheel, and those on the opposite side pass upedgewise against the current. This action being kept up by the current,the wheel will give a power sufficient to run any desired machinery. Itis obvious that the wheel may be connected to the machinery which it isdesired to operate in any suitable manner. W`hen it is desired to stopthe wheel, the rod i is pulled up, which in turn raises the cross-beam Iand sleeve G by means of extension g. This raises the locking-bars IIand H', thus bringing the notches 7L and h directly behind theprojections c and f, respectively, thus taking away the support of saidprojection. The paddles, having no support, swing edgewise with thecurrent, thus offering no resistance. Consequently the wheel stops. Whenit is desired to start the wheel again, the rod is lowered, thuslowering the locking-rods II and Il. Thus the notches 7L and it are letdown below the projections e and f, and the projections again bearagainst the rod. The current will again revolve the wheel, as above setforth. It will be understood that the lifting-rod i may be connectedwith any suitable gearing for lifting.

It is evident that many slight changes and alterations may be made inthe relative construction and arrangement of parts without departingfrom the spirit of our invention. Hence we would have it understood thatwe do not confine ourselves strictly to the parts herein described.

Having fully described our invention, what we claim, and desire tosecure by Letters Patent, is-

l. The combination, with the series of paddles having lugs on theirinner ends, of the sleeve having extensions, one of which is slotted,the locking-rods provided with notches, and the cross-beam suitablyconnected to a lifting-rod, substantially as described.

2. In a water-wheel, the sleeve having extensions, one of saidextensions being slotted, the alternate long and short locking-rodshaving notches, the cross-beam connected to the sleeve and a suitablelifting-rod, and an upper and lower series of paddles having lugs orprojections, the whole secured and operating in a suitable frame,substantially as described.

3. In a water-wheel, the frame, a cross-beam pivotally secured to saidframe and connected to a lifting-rod', the sleeve having extensions, oneof which is slotted, the said sleeve working around a shaft and securedto the crossbearn, the long and short locking-rods having notches, andthe upper and lower series of paddles provided with lugs or projectionswhich engage 'the locking-rods, substantially as described. D

4. The combination, in a water-wheel, with a frame having grooved sidepieces. the shaft C, the cross-beam pivoted to one of the side pieces ofsaid frame, a lifting-rod secured to said beam, the sleeve G, havingextensions g and g', the extension g being slotted, the alternate longand short locking-rods having notches, the slotted plates D, between'which the arms D are Secured, a vertical standard d and ring CZ,connecting the arms D', and the paddles having projections engaging thelocking-rods, the said paddles being hinged to the standards el',substantial] y as described.

In testimony whereof we affix our signatures in presence of twowitnesses.
